wife shared way more eye contact with the other woman than with the man, my ego is in pieces and idk why

wife and I are bi-curious wife / straight husband setup, in the LS about two years, we usually meet bi-friendly couples bc thats the dynamic she wanted to explore. last weekend we had a meet with a couple where the wife was clearly experienced with women and my wife really clicked with her. fine, expected, encouraged actually. the issue is the eye contact thing. like during the entire scene, even when my wife was being touched by their husband, she was looking at the other wife. mostly. and the other wife was looking right back. I was kinda just there?? doing my thing with their wife but watching this whole nonverbal conversation happening between the two women and it was clearly more intense than what I was experiencing physically with anyone in the room. now Im 5 days out and Im weirdly insecure about it. like Ive made peace with my wife being into women, thats part of why we are in the LS at all. but Ive never seen her connect to another woman LIKE THAT and it felt different from when she connects with a man we play with. it felt deeper. it felt like the LS but with a layer I dont know how to be in. am I jealous of a woman?? thats new territory for me. is this gonna be a recurring thing if we keep meeting bi-friendly couples?? how do you guys, the husbands of bi-leaning wives, exist in that energy without feeling like a side character.
